Lette rs PatentNo. 102,895, dated May 10, 1870.

- IMPROVEMENT m LANTERNS.

The Schedule referred to in .these Letters Patent and making part of the same.

To all whom it may concern Be it known that I, WILLIAM Wnsrnann, ot' the city of Chicago, in the county of Cook and State of .Illinois, have invented certain new and useful Im- The nature of my invention consists in forr'ning a pressure inside of a lantern-globe; in providing a separate chamber for the wick; and in the several parts and combinations claimed as new.

The object of my invention is to produce a lantern that shall produce a most perfect light, and which at the same time can be used out of doors without being afl'ected bycurrents of; air orwiud.

To enable others skilled in the art to make and use my improvements, I will describe the construction and operation of the same.

. The glass globe A is made in any of the known forms, and provided at or near the top with tubular openings or projections R, over or into which. the upper ends of the metallic tubes D are placed.

The base of the lantern is made of a vertical band, B, and flange or base-band O. No especial form or configuration ofthe base is essential, and it may be varied as desired.

In this base, I place'at the bottom an air-chamber, if], as shown at fig. 4, and by the dotted lines in If desired, this chamber may be made'tocover the entire base of the lantern, by extending the tubes L through it, but, as ordinarily made, it only extends to the openings for the tubes L, and across the bottom. The tubes L pass through the oil-reservoir, and are open top and bottom, as shown.

The lower ends of the tubes or pipes I) enter this chamber, or opeu'into it, and the air which passes into E passes into the chamber or annular space S, which surrounds the tube N, and from, this through the burner g, and under the cap or cone K to the flame. V The burner g is fitted to the tube'N.

This tube holds the wick, which passes through I), and is filled with oil by means of the small tube 0, locat-ed near its bottom, which, wit-lithe tube (7, connects it with the oil-reservoir. V

f is simply an additional Support forN, hut,'if desired, it may also be made tubular.

accompany- The oil-reservoiris the annular space between the bands 0 and B, which is covered at the .top by the disk or plate M, and at the bottom by P, and, in ii"- ing, the oil'is poured intothe tube N, and from that it passes throug'hc into the reservoir, while the air escapes through the tube (1.

0 represents the ratchet for operatingathe wick. The band B projects sufliciently above the disk M v to hold the bottom of the globe in place.

The tubes or pipes D are made of tin or other suitable material, and are firmly attached to the base, as shown.

At theirupper ends they connect with the project-ions R ofthe globe, so as to be easily detached, and allow the globe to be detached 'fo the purpose of repairs, cleaning, or lighting the lamp, or .they may be so attached to the base as to spring off when the band or ring J, or-other device for holding them, is removed.

The bail or handle Q is also attached to, them, as shown.

The cap or dome is made separate and removable, and is secured in place by means of the hook andpln a,orby any other suitable means, and it is made of two plates h and G. e

The plate or cup 11 is spun or stamped up, as shown,

and so attached or supported as to leave large spaces, as showp, forthe' escape of smoke, 8:60.

The plate G covers the entire top of the globe, and has no perforations.

Into this plate GI insert tubc H,'whieh is about one inch'in diameter, and extends downward into the globe aboutone-third of its length, as shown.

A-cap or deflector, I, issuspended beneath the tube H by wires, about the distance of one,-half of an inch. \Vhen the dome or cover is removed, the tube H is removed with it.

By this method of constructing and arranging the dome and the tube .H with its cap I, it will be seen that any air which enters the openings in the cap E will be likely to pass out-on the opposite side, instead of passing down the tube H, and that, if by any means any portion of the air should pass down the tube H, it will impinge on the capor deflector I, which will cause it to pass off laterally, and thus prevent it from aifectin g the flame.

In operation, the air passes directly into the lantern through the tubes L insuflicient quantities to fill the presses a current of air out of the openings B through the tubes D into the air-chamber E, and from that to the flame. This operationis continuous. Fresh air is supplied by the tubes L, and these may be aided byv perforations in the band B, if desired.

Having thus fully described my improvement, \Vhat I claim as new, and desire to secure by Letters Patent, is-- 1. The dolne or cap, when provided with the tube H, in combination with the globe A, substantially as and for the purposes specified.

2. The cap or deflector I, in combination with the tube H, substantially as described.
